Remove an Application Setting (IIS 7)

Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista

Remove an application setting when you no longer want to store key/value pairs as part of your configuration in the Web.config file. You can remove an application setting at a local level or you can remove an application setting that is inherited from a parent level.


Removing a configuration setting removes the setting at the local level and from any child levels that inherit the setting.


For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required to perform this procedure, see Application Settings Feature Requirements (IIS 7).

You can perform this procedure by using the user interface (UI), by running Appcmd.exe commands in a command-line window, by editing configuration files directly, or by writing WMI scripts.

  2. In Features View, double-click Application Settings.

  3. On the Application Settings page, select the application setting you want to remove, click Remove in the Actions pane, and then click Yes.


To remove an application setting, use the following syntax:

appcmd set config /commit:MACHINE /section:appSettings /-"[key='string',value='string']"

The variable key string is the name of the application setting and the variable value string is the value for the application setting. For example, to remove an application setting for the application named "MyApplication", type the following at the command prompt, and then press Enter:

appcmd set config /commit:MACHINE /section:appSettings /-"[key='Application Name',value='MyApplication']"
